Abstract: Objective To study the epidemiologic characteristics of virus-induced acute diarrhea in children under 5 years old in Taiyuan, Shauxi province. Methods Stool specimens and clinical data were collected from 346 inpatients with acute diarrhea from children less than 5 years old. Rotavirus-positive specimens were identified by ELASA kit. Calicivirus and astrovirus were detected by reverse transcription-polymerase chain reaction (RT-PCR);Adenovirus was done by polymerase chain reaction(PCR). Results Of the 346 specimens, the percentage of samples with Rotavirus, Calicivirus, Astrovirus, and Adenovirus was 40.8%,7.5% , 6.4% and 3.2%. Among 141 rotavirus positive samples, serotype G1 (42.6%)was the predominant strain. More than 95% of viral diarrhea patients under hospitalization occurred among children younger than 2 years. Conclusion Rotavirus is the major pathogen contributing to the acute diarrhea. The disease is generally peaks at autumn/winter. The predominant rotavirus strain circulated was G1P[8].
